[PATCH] device-mapper: use dynamic debug instead of config option

[PATCH] device-mapper: use dynamic debug instead of config option

[Hannes Reinecke]

Debugging device-mapper via the DMDEBUG() call is currently depending
on the CONFIG_DM_DEBUG option and needs a recompilation to activate.
This patch replaces the config option with dynamic debugging to
enable debugging without recompilation.
